Instead of expensive platinum etc, a metal-free alternative catalyst for fuel cells may be at hand. A team of chemists from University of Wisconsin-Madison introduces a new approach that uses a molecular catalyst system instead of solid catalysts. Although molecular catalysts have been explored before, earlier examples were much less efficient than the traditional platinum catalyst.
A fuel cell converts chemical energy into electricity by reacting H2 and O2 at 2 different electrodes. A catalyst makes the reaction more efficient.
